Well yes if you want the timeline to be right, but the experience will be different. Personally I read Dokgo first without knowing anything prior and then read the prequel, and I think that was the best way to do it. The prequel would have ruined some of it for me, I think, but people always have different opinions on this (like w/ star wars)
If dokgo rewind is the prequel and the movie for this will come out first, why do I have to read the Dokgo first? The right order wouldn't be dokgo Rwind, dokgo and then dokgo 2?
